Stress!: A stressful confrontation will often activate the "fight or flight" response that prepares you to defend yourself & evade danger. Your pupils dilate to let in more light, blood is sent to muscles, & the heart works harder and faster to move the blood where it belongs. Your awareness of your heart beat may vary with stress & anxiety - undetected while exercising, but loud when upset.
